A toner for electrostatic image development comprises components of a charge control agent, a binding resin, and colorant. The charge control agent is an aromatic-oxy-carboxylic acid iron-including compound. The toner has its particle size distribution with: a volume-average particle diameter (D50) ranging from 5 to 13 microns that is determined by a cumulative 50% volume particle diameter from alargest particle diameter, and a degree of particle size dispersion (D25/D75) ranging from 1.20 to 1.50 that is calculated by a cumulative 25% volume particle diameter (D25) and a cumulative 75% volume particle diameter (D75) as same as the above determined D50.
